Postoperative complications of pulmonary resection after platinum-based induction chemotherapy for primary lung cancer

We investigated the postoperative complications that developed in patients who underwent surgery after induction chemotherapy (IC) for primary lung cancer. Twenty-seven patients underwent surgery after receiving IC; for advanced non-small cell lung cancer in 16, and for small cell lung cancer in 11. All patients were given the platinum-based chemotherapy regimen. Lobectomies were performed for 18 patients, bilobectomies for 4, pneumonectomies for 2, and partial resections or segmentectomies for 3. There were two postoperative deaths; one caused by adult respiratory distress syndrome (ARDS) and one caused by respiratory failure, resulting in a mortality rate of 7.4%. The postoperative complications included sputum retention in six patients, ARDS in two, anastomotic dehiscence after bronchoplasty in one, and pneumonia in one, resulting in 44.4% morbidity. The morbidity of patients who had received IC (IC group) was higher than that of a comparative group of 560 who underwent lung resection without IC during the same period (non-IC group), but the difference was not significant (44.4% vs 22.6%; P = 0.16). Both ARDS and bronchial insufficiency occurred more frequently in the IC group than in the non-IC group, but the differences were not significant ( P = 0.25). These findings indicate the feasibility of treating primary lung cancer with IC followed by surgery as long as a cautious operative procedure is used and careful postoperative management is given, paying particular attention to the risk of ARDS and bronchial complications.
